Part 7/10:
Musk has suggested alternative means of food production, such as hydroponics; however, Martian soil toxicity complicates such methods. The potential for energy generation via solar panels on Mars is dimmed by its distance from the Sun and frequent dust storms, stymying efforts to sustain a million settlers with agricultural output.
Nuclear power could be a more reliable option, albeit with its own risks. As for food production, the possibility of sustaining a million people with a diet primarily consisting of hydroponic vegetables presents significant challenges and raises questions about dietary diversity.
